re i engagement with the retaining plates.

leaf spring 11 which is clamped by the head of the bolt 4 against theclamp body. The

spring serves to maintain the reduced end y 10 of the plate 10 inengagement with the cam 8. Said cam has two diametrically oppositearcuate dwells 8 that are coaxial with the jaw stem 7. It also has twodiametrically opposite concave actuating portions 82 that are locatedbetween the parts 8. When either of the dwells 8 engages the plateportion 10.', the plate 10 is thrust outwardly from the axis of the jaw6 against the force'of the spring 11 and when either cam portion 82receives the plate portion l. 10", the plate 10 is moved toward the stemof the jaw by the spring 11 to the extent permitted by the cam.

The adjusting plate 10 is formed with dey pending fingers 102 that enterthe slots or recesses 12 in the retaining plates 12 which are employedto hold the body Vof the clamp `within the groove 13% of the bed 0r formsupportj14, the Vplates 12 being movable transversely ot' the clamp bodyand being projectable laterally thereof at their longithat one of themfully receives the adjusting plate portion 10', the wedging fingers 102then causing the retaining plates to move together to bring the outerlongitudinal edges of these plates flush with the sides of the yclampAbody. When these retaining platesare thus drawn inwardly toward eachother, the clamp body Vmay be inserted into the selected one of theparallel grooves 13 formed in the bed support 14, this groove A- beingof just suchV depth Vas to bring the platesl 12 into the plane of theslots 15 formed in the sides of the groove 13, these slots being just ofsuiiicient depth to snugly receive the outer longitudinalsides of theseplates when the jaw 6 is turned into a work holding position such asillustrated in Figs. '5, 7, 8 and 9, the jaw7 in being brought intoyits-work holding position, forcing the adjusting plate 10 outwardlyuntil its cam engaging portion 10 is engaged by one of the dwells 8. Thework holdingjaw 6 is then held from vertical displacement and close to lthe work support 14 to take part in holding 'the rpla-te or work 16close upon its support.

vThe clamping device is also dcsirably adjustable 1n thefgroove 13 thatreceives it so that its location may be readily changed to suit thelocation of the printing element 16. lhen the clamp is thus constructed,I provide sectional threads 17 in the lower parts of the grooves 13,these threads being in the nature ot racks. A worin screw 18 is mountedupon the stem of the bolt 4 and is free to turn on and with respect tosuch stem, said worin screw being in thrusting relation to the body ofthe clamp so that when the screw is turned the clam will be forced tomove along the groove in which its body is received. Said screw isdesirably turned by means of two .interineshing bevel pinions 19 and 20,the pinion 19 being housed by the body member 2 and rotatable thereinwhile the pinion 20 is desirably directly formed upon the body of thescrew 18. The pinion 19 is coaxial with the jaw stem 7. Said jaw stem isprovided with a cylindrical bore 21 while the pinion 19 is provided witha square bore 22 that is in alignment with the bore 21. A square wrenchmay be passed through the bore 21 into the bore 22 in order to turn thepinion 19 to turn the screw 18 and force or ellect the travel of theclamp.

In the use of the clamping device, the body thereof is placed in thegroove 13 that receives it in close proximity to the work that is to beheld, the actual clamping engagement of the clamping jaw with the workbeing effected by turning the screw 18 in the manner described. Whilel Ihave illustrated the bed or form support 14 as being flat, it is to beunderstood that the clamp of my invention is not to be limited to such aflat support.

My copending applications Serial No. 257,406 and Serial No. 257,407.filed February 27, 1928, disclose printing press beds upon which theclamping device herein disclosed may be employed.

Changes may be lnade without departing from the invention.
